Pulse Amplitude Modulation(PAM): Pulse Amplitude Modulation(PAM) is the simplest form of Pulse Modulation. It is shown in Fig. 18.7. PAM is a pulse modulation system in which the signal is…
Data Logger Operation: Data Logger Operation - For proper understanding of a Data Logger Operation, it is essential to understand the difference between analog and digital signals. For example, measurement…
DA Converter Working Principle: The resistive divider or ladder can be used as the basis for a DA Converter Working Principle. It is in the resistive network that the actual…
Weighted Converter Using Transistor Switches (Current Switch): Figure 17.19 (a) shows a circuit diagram of a weighted converter, using transistor switches. When the D bit is high (logic 1), it…
Binary Ladder Circuits: A Binary Ladder Circuits is constructed of resistors having only two values and thus overcomes the disadvantages of weighted resistors. The left end of the ladder is…
Single Channel Data Acquisition System: A Single Channel Data Acquisition System consists of a signal conditioner followed by an analog to digital (A/D) converter, performing repetitive conversions at a free…
Nonlinear Distortion Measurements: One of the methods of Nonlinear Distortion Measurements consists of simultaÂneously applying two sinusoidal voltages of different frequencies to the amplifier input and observing the sum, difference…
Sensitivity Measurement Definition: The Sensitivity Measurement Definition of a radio receiver is its ability to amplify weak signals. It is often defined in terms of the voltage that must be…
